5 claims. (ci. 15a-9) This invention relates to vehicle seats and its thereof and upon which are journaled rollers 5 general object is to provide a 'seat that ispriarranged in pairs and mounted upon the base j marily designed for use in passenger airplanes of the rails as clearly shown in Figure 2. and the like to relieve the shock imparted to the The legs preferably form a part of a tubular 5 occupants, caused when making abad landing base frame of the seat which includes cross pieces or in the event of a crash or crackup, thereby 6 that have welded or otherwise secured thereto preventing or reducing injury to a minimum in the body 'I of the seat, the body including a seat that the seat is mounted for movement butis reportion 8 and a back 9 which together with the strained or checked during its movement an c i l seat portion and the sides areY preferably formed 1u brought to a gradual stop within a short space; into a single unit, as suggested in Figure 1. It l0 thereby preventing the occupant from being will be'obvious that the body of the seat may be thrown from the seat or jolted about therein.` upholstered and provided with suitable cush- A further object of the invention is to provide ions and any means may be employed for ata seat of the character set forth,V that is simple in tachingl a safety belt to the body.

in the appended claims. Cooperating with the anchor bar I isaI bar In describing the invention in detail, reference I2 which bridges and is fixed at its ends to the will be had to the accompanying drawing whereinner'side of `the tracks, it being obvious that a 25 in like characters denote like or corresponding bar I2is provfded for each seat, and the bars I2 v parts throughout the several views, and in which: are disposed at equi-distantly spaced relation Figure 1 is a vertical sectional view taken along the tracks.

The reCtOrl 0f the al'rOWS- cover members have grooves arranged therein to Figure 3 iS e SeCtiOnal View teken aIJD10Xi 'act as seats for the looped end portions of an 35 mately on line 3-3'of Figure 1,-lookingin the elastic cord |5, the 1am-,er having one end ,fixed direction 0f the arrows to the bar I0 aboutthe cover member thereof Figure 4 is a fragmentary detail View illus' and is thence looped about the bars, with itsoptrating the rear portion of the seatjand itsapposite end likewise xed to the bar I2 and about o plication t9 a track Wm? parts in section ,andthe cover member thereof. The looped portionsin elevation' of the cord adjacentY to the bars are secured to- Referring to the drawing in detail, the refergether as .at It ence numeral I indicates a pair of tracks, and Cooperating with the elastic cord which of while only one seat and one pair of traks are course acts in the capacity as a shockabsorber, I6 shown, it will be obviousthat in regular passenare Snubbes n in the form of cams having er carrying planes two pan' f tracks Wm be rounded faces provided with teeth Is extending installed which are lprefemily fasted C u? transversely thereof and the snubbers include cross struts of the p ane. ny num -r o vsea s are mounted on the tracks, it depending of course 'dxdbteiggses Vlmflraldprlolgltles 60 u n the size of the plane, as will be apparent.

p'(1)'he tracks as best shown'in Figure 2 are of xed to the rear portions of the front legs, as

the channel type and include overhanging horibest SHOW!! in Figures 1 91H13, and in a manzontal spaced flanges 2 between which are passed 11er whereby the teeth I8 normally rest HPO!! the forward and rear legs 3 and l' respectively, the the flanges of the tracks, and are held accordlegs having stub axles fixed to theA lower ends ingly by coil springs 2|, the latter having one of 55 their ends fixed to the snubbers and the opposite ends to the front legs.

I likewise provide a foot rest it being obvious that the foot rest is designed for the occupant of the seat to the rear of the one shown, and the foot rest not only acts as such, but also to hold the seat against casual movement, as well as a. cover, in that it includes na fiat upper wall 22 having side walls 2 3 secured thereto, and the side walls have ears 24 formed thereon adjacent the upper ends, the ears being pivotally secured to the inner sides of the rear legs, for securing the foot rest to the seat accordingly, as will be apparent upon inspection of Figure 4, which likewise illustrates the fact that the upper wall is disposed at an inclination to lprovide a convenient rest. Secured to the under surface of the upper wall is a pair of bracket members 25 that terminate at their lower ends in semi-circular members 26 to iittingly engage the bar i2. therefore it will be obvious that the foot rest prevents casual movement of the seat and the brackets are held accordingly by coil springs 21, the latter having one of their ends secured to the side Walls and their opposite ends to the rear legs.

From the above description and disclosure of the drawing, it will be obvious that I have provided a seat that is mounted i'or movement, and is primarily designed for use in passenger airplanes or the like, but of course can be used in any type of vehicle. In any event if a vehicle equipped with my seats should be suddenly stopped, the bracket members 25 would become disengaged from the -bar I2 and the seat would be moved forwardly on the tracks, but of course the movement would be checked or restrained by the action of the cord or cords I 5, as well as by the snubbers l1, and brought to a gradual stop, thereby preventing the occupant fromr being thrown from the seat and becoming injured.

While I have illustrated and described elastic cords and tracks of a certain type, it wi1l.of course be understood thatcoil springs or other suitable resilient means can be used in place of the cord or cords, and tracks of any kind suit= able for the purpose maybe employed.

It is thought from the `foregoing `description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims. f

What I claim is:

l. A seat comprising a body including a seat portion and a back, a base carrying the body, rollers onthe base tracks for the rollers, stretchable resilient means having one end fixed to the base and its opposite end anchored to limit movement of the seat on the tracks, and toothed snubbing means pivotally mounted on the base and engaged with the tracks for cooperation with the resilient means to check and gradually stop movement of the seat.

2. A seat comprising a body including a seat portion and a back, a base carrying the body and including legs, rollers Journaled on the lower ends of the base for movement oi' the seat thereon, tracks having the rollers bar bridging the front legs, stretchable resilient means having one of their ends secured to the bar and the opposite ends anchored to limit movement of the seat with respect to the tracks, and toothed snubbing means on the front legs and engaged with the tracks for cooperation with the resilient means to check and gradually stop movement of the seat.

3. A seat comprising a body including a seat mounted thereon, a g

pivotally mounted 1| portion and a back, a base carrying the body and u including front and rear legs, rollers on the lower ends of the legs, tracks having the rollers mounted therein for movement ofthe seat along the tracks, a bar bridging the front legs, stretchable resilient means having one end fixed to the 20 bar and the opposite end anchored to limit movement of the seat, toothed snubbing means pivotally secured to the front legs and engageable with the tracks i'or cooperation withf the resilient means to check and movement of the seat. 4. A seat comprising a body including a seat portion and a back, a base carrying the body and including front and rearlegs, rollers journaled gradually stop 25 to the lower ends of the legs, tracks receiving 30 the rollers for movement of the seat with respect thereto, a cross bar bridging the front legs, a cross bar bridging the tracks, stretchable resilient means having the ends thereof xed to the cross bars to limit the movement of the 35 seat, snubbing means pivotally secured to the front legs and engageable with the tracks for cooperation with the resilient means to check and gradually stop movement of the seat, and

a foot rest pivotally secured to the base, and 40 engageable with the cross bar of the tracks to normally hold the seat against movement.
